years from that of *TC and Taipei #+# • ,assive jump in height possible of buttressed &ore stru&tural system • Design employs &onventional &onstru&tion te&hni-ues

• As building rises2 ea&h .ing setsba&k in &lo&k.ise

 pattern • Tapering minimises .ind effe&ts and organisation of .ind vorti&es • Give and take bet.een &ore and .ing makes system more stable

CONSTRUCTION OF CORE • A&tually made of not pure &ement or &on&rete • 3ly ash is the key &omponent/&ost effe&tive2 energy saving2 &onservation of resour&es • Tri/a%ial design &onsists of three tiers that are staggered throughout &onstru&tion of ea&h floor as the  building rises • )/tier design allo.s the .ind to not hit one side dire&tly or head on2 diverting the .ind from the

hitting the building straight on at any point

HEXAGONAL HUB • ,ost &ru&ial aspe&t • "i% sided &entre pie&e • A&ts as an a%le that en&loses the elevators • A&ts like a tube surrounding the building and makes

stiff  • torsionally Thi&kened hammerhead .alls lo&ated at the end of the &orridors running do.n through the .ings  prevent the building from t.isting about its verti&al a%is be&ause of moments of inertia
